SAMUEL B. DAVIS, or HAMBURG, IowA.

Ill/l PROVENlENT IN Eb-PLANTi-fia Specification forming'part of Letters Patent No. 203,122., dated April 30,1878; application filed January 15, 1878.

. hereby declare that the following is a full, clear, and'exact description thereof, reference being had to the, accompanying drawings, and

to the letters of reference marked thereon,

which form part of this specification. l

The nature of my invention consists in the construction and arrangement of a seedeplanter, as will be hereinafter more fully set .forth.

In order to enable others skilled inthe art to which my invention appertains to make and use the same, Iwill now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a plan view of myimproved seed- Fig. 2 is a longitudinal section of the same. Figs. 3 to 9 are detailed views of parts thereof. I

A represents the axle, with driving-wheels B B placed upon its ends. To the axle A are secured four parallel beams, O O and G 0}, connected a suitable distance in front of the axle by a beam, 0 running parallel with the axle.

The two center beams (J O extend a suitable distance in rear of the axle, to support the seat E; andin front said beams extend a sufficient distance forward of the beam 0 to have the tongue D secured between them. Upon the frame thus constructed is a frame, G, hinged at its front end, and in suitable bearings upon said hinged frame is placed a crankshaft, H, having a pinion, a, on each end, which pinions gear with similar pinions b b secured upon theinner ends of the hubs of the driving-wheels B B. The rear end of the frame Gr is raised to throw the wheels at and b out of gear by means of a lever, I, pivoted on the rear of said frame, and working against'aplate or bar, d, on the main frame. When the said cog-wheels are thrown in gear the frame G is held down upon the main frame by means, of hooked levers J J, pivoted to the main frame and made to engage over the shaft H. l

K K represent the corn-boxes, provided with downwardly-extending conductors L L,

and secured to and connected bya bar, M, whichyis secured to two metal frames, N N, one at each end. The front ends of these frames are hinged in eyebolts 'e e on the bar 0 Each frame N is constructed to receive a circular rolling colter, O, placed upon a bolt therein, directly in front of a mold .or furrow opener, P, which issecured to the front at the lower end of the conductor L. V p

. It represents the covering-wheel in rear of each conductor L. This wheel is mounted on a pin or bolt passing through therear ends of two L-shaped arms, S. S, which are fastened at their angles by a single bolt or pin, f,

passing through the rear side of the conductor,

said arms being placed one on each side thereof. The upper ends of the arms S Shave bars h h pivoted to them, and the front ends of said bars fastened by bolts to the under side of the bfilT'M- The bars h are perforated, so that their connection with thebar M can be changed, and the arms S thus turn uponthe pin f as upon a pivot, whereby the covering wheel or roller B can be adjusted up or down. to regulate the depth in the ground that the seed is to be put, and then covers the seed. The mold or opener P that follows the rolling colter 0 divides the ground so that the corn drops into the ground through the; spout or conductor L, and then the wheel R covers it.

' It will be noticed .that the rolling colters, corn-boxes, molds, spouts, and rollers are all connected together. l l

To thebar M is attached a bail, T,which is connected to the rear. end of a lever, V, pivoted in a forked stud, 1', under the axle A. The front end of the lever Vis operated upon by a crank-lever, W, whereby the planting mechanism-4. a, hoppers, colters, coveringwheels, &c.-may be raised and lowered as required. u M H In the frontof, each box K, on the inner side, is a recess to receive thecircular droppingplate Y, in which are two holes,and in each hole is inserteda bent metalxplate ;orstrip,

16, to form, the dropping-pocket. The outer side of the plate Y-thatis, the side toward the front of the -machine is recessed, as shown in Figs. 4 and 5, and the upper ends of the strips 70 are fastened in said recess to the plate by setscrews m. They are then bent, as shown in Fig. 6, and pass through toward the inner side of the plate Y, to form the dropping-pockets. The bottom Z of the box is inclined from front to rear, and formed with a central ridge, to form, as it were, two grooves for conducting the corn to the dropping-plate. The dropping-plate Yis covered by a plate, A, inside the box, which plate A is attached to the bottom Z, and provided with two holes, a: 00, through which the corn passes to the pockets. Below these holes are cut-off slides p 19, which are flanged at their front ends. These cutoffs pass horizontally through under theinclined bottom Z,

. and their rear ends are V-shaped and acted upon by a spring, n, which forces them forward.

The dropping-plates Y are rocked upon -central pivots r by devices hereinafter described, and as each pocket, in succession,

passes below the bottom Z, the corn drops into thespout or conductor L, the cut-offs p p, actuated by the spring n, preventing any grains of corn from getting in between the operating parts.

The strips Ir, which form the droppingpockets, can be adjusted through openings y 3 in the front of the box by means of the setscrews m m, so as to drop more or less at each time, as may be desired.

In the lower part of each dropping-plate Y is a radial slot, 8, through which passes one arm of an L-shaped rod, B.

This arm also enters a fork, t, attached to the upper end of a Valve, D, pivoted in the spout or conductor L, whereby the corn is arrested in said spout,

and afterward dropped directly into the furrow in the usual manner.

The inner arms of the L-shaped bars B B lie on the bar M, and are fastened in grooves on the under side of a bar, F, which slides back and forth in keepers o v on top of said bar M. The under side of the bar F is cut out in the center, and at each end of said outout or recess is pivoted a friction-roller, w.

G represents a connecting-bar, of substantially the form shown in Fig. 2. The rear end of this bar is flattened, and has on each side an inclined wing, H, and in the center a longitudinal slot, at. This portion of the bar G passes between the rollers w w in the recess of the bar F, and a pin, 1), projects from the bar M into the slot a, to guide the movement of said barG.

Itwill readily be seen that if the bar G be moved backward and forward the wings H H, acting alternately upon the rollers w w,

will move the slide F with the rods B B 'alternately from-side to side, and thereby operate the dropping-plates Y and valves D.

The front end of the bar G is adjustably connected to the lower end of a lever, I, which is pivoted in the end of an arm, J, secured on the front of the main frame, and the upper end'of said lever I is, by a pitman, L,

connected with the crank in the center of the crank-shaft H, whereby thus the dropping mechanism obtains its required motion. .On the crank-shaft H is secured an index-wheel, K, numbered so as to showv where the drop is made. An index, at, is secured to the frame G, to point on said wheel D, number 0 being the point at which the drop is made. The numbers on this wheel indicate the distance in inches from the bar connecting the boxes to the point at which the stakes should be set. The stakes are to be set up at the point indicated to show where to start in on the next two rows. to show the proper distance at which they are to be set from said bar. S S are the graduated stakes, which are carried on the machine by being inserted in suitable keepers on the sides of the hoppers. The drivin gwheels B B are constructed of the usual hubs and spokes. The rim of each wheel is made in one piece with sockets h for the tenons of the spokes, points i opposite said tenons, and concave edges m between the points.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the hopper or box K, having apertures y in its front side, the reciprocating rotating dropping plate Y, perforated as described, and the strips k k, adjustably arranged on the plate Y, and in the perforations thereof, by means of the screws m, which are opposite the apertures y in the box K, whereby the strips kmay be adjusted from the outside of the box, substantially as herein set forth.

2. The combination of the box K, rotary reciprocating dropping-plate Y, the stationary vertical plate A, inclined bottom Z, and flanged cut-offs p p, actuated by the spring a, all substantially as and for the purposes herein set forth.

3. Thecombination, in a planter, of the bar G, opera-ted from the crank-shaft H by the pitman L and lever I, and provided with the longitudinal slot a and inclined side wings H H, the bar M, having pin 1) passing through the slot or in said bar G, the recessed slide F, having friction-rollers 'w w, the L-shaped rods B, dropping-plates Y with slots 8, and the valves D with forks t, all

constructed and arranged substantially as and two witnesses.
